       Delete  keyword  entries  from the header of FITS or IRAF image[s].  If a keyword does not already exist,
       ignore it.  To delete keywords in a list of files, substitute @<listfile>  for  the  file  names  on  the
       command  line.   To  delete  a  lot  of  keywords,  put  them,  one  per  line,  in a file and substitute
       @<keylistfile> on the command line.  If two @ commands are present, the program  will  figure  out  which
       contains file names and which contains keywords.
